• Render buffer: a flattened version of the render, including the contribution of all the emitters together as they got adjusted when the render was finished. For reference purposes. It also details the Sampling Level reached when that render was stored.
• Light buffers: if the render has been launched with the MultiLight feature enabled, then each individual emitter will be imported in Photoshop as an independent layer, to allow further adjustments.
• Shadow buffers: if the render has been launched with the MultiLight feature enabled, and the shadow channel activated, each individual light will have an independent shadow buffer.
• Extra buffers: if the render includes extra buffers, which you have to enable when you launch the render, they will be imported as individual layers. The render buffers include Alpha, Z-buffer, Object Id, Material Id, Fresnel, Roughness, Motion Vector, Normals, Position, UV and Custom Alpha.
